Can a vanadium redox flow battery be a high-performance battery?

Vanadium redox flow battery (VRFB) has garnered significant attention due to its potential for facilitating the cost-effective utilization of renewable energy and large-scale power storage. However, the limited electrochemical activity of the electrode in vanadium redox reactions poses a challenge in achieving a high-performance VRFB.

What is a redox flow battery?

The most common and mature RFB is the vanadium redox flow battery (VRFB) with vanadium as both catholyte (V 2+, V 3+) and anolyte (V 4+, V 5+ ). There is no cross-contamination from anolyte to catholyte possible, and hence this is one of the most simple electrolyte systems known.
